Polyacrylamide degradation and its implications in environmental systems | npj Clean Water - Nature

The term ¡°polyacrylamide¡± is loosely used to describe any polymer with acrylamide present as one of the monomers. 1 More rigorously, its IUPAC nomenclature is poly (prop-2-enamide), which...

ANIONIC POLYACRYLAMIDE - Santos

Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

polyacrylamide

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

Water Soluble Polymer Flocculants: Synthesis, Characterization, and Performance Assessment - Vajihinejad - 2019 - Macromolecular Materials

Polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly (vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7

molecular mechanisms of ultrafiltration membrane fouling in polymer-flooding wastewater treatment: role of ions in polymeric fouling

Molecular Mechanisms of Ultrafiltration Membrane Fouling in Polymer-Flooding Wastewater Treatment: Role of Ions in Polymeric Fouling

Polymer (i.e., anionic polyacrylamide (APAM)) fouling of polyvinylidene fluoride (PVDF) ultrafiltration (UF) membranes and its relationships to intermolecular interactions were investigated using atomic force microscopy (AFM). Distinct relations were obtained between the AFM force spectroscopy measurements and calculated fouling resistance over the concentration polarization layer (CPL) and

Anionic polyacrylamide efficiency in goethite removal from aqueous solutions: goethite suspension destabilization by PAM - International Journal

11 Citations Explore all metrics Abstract The main aim of the study was to investigate the anionic polyacrylamide (PAM) efficiency as a flocculant relative to goethite particles. This mineral is a toxic waste produced during hydrometallurgical processes and, as a result, poses a threat to the environment.

Treatment of Toxicant Dye Compounds in Wastewater by Modified Natural Coagulant

An anionic polymer such as anionic polyacrylamide gets a negative charge when its ionic groups dissociate in a medium. It is known as an amphoteric polymer which can be initiated using active anionic species such as hydroxide, sodium or cationic species such as sulphuric acid and hydrochloric acid.
